Eh, it's not an unreasonable stance to take. The companies, work environments and people who made these previous games are not the same as they are now; regardless of how good their intentions are (particularly Yu, who I know has been so eager to conclude the Shenmue story) it's unrealistic to expect these games to fulfill everyone's dreams, or for archaic design ideas to not be critiqued by a harsher, more judgemental new generation of gamers. Especially here on NeoGAF, you just KNOW that people are going to swing to the other extreme, fill the forum with threads about these being the biggest disappointments of all time, no matter what. And that's not even taking into account any additions that ultimately end up tarnishing the final product, be it a shortage of funding or just boneheaded attempts to "modernise" the gameplay in a cynical ploy to appeal to more people than before. And let's not entertain the idea of potential retcons showing up.
I think it's perfectly fine to REALLY look forward to these games though, and the article itself even admits that. They're exciting, almost legendary game announcements, and for whatever happens to them, it's nice that developers are finally delivering the things gamers have been asking for for such a long time. With that in mind, I don't think it's giving in to nostalgia, so much as fulfilling demands of the consumers.
